Our felt car fresheners are sublimated in house. We add your business name to the back of the car fresheners or they can come with the same design on the front and back. For car fresheners without logo or business name just leave the customizable box blank. Car fresheners are 3x4 inches. Designs last forever. Scents last 3-4 weeks. Scents can be added to the car fresheners after by essential oils or our add-on spray bottles. Car fresheners come with hangers, bagged individually, and with a sticker of the scent on the back. These are to be hung on rear view mirrors.
